Authorities launched a massive operation Wednesday morning to target a drug and weapons ring in Wilmington being orchestrated by the Wilmas Gang and affiliated with the Mexican Mafia.

Operation Tidal Wave was part of a three-year investigation and resulted with more than two dozen men and women being taken into custody.

"The indictment names 29 individuals, 10 of which were already in custody," Special Agent Timothy Massino with the Drug Enforcement Administration explained.

At least 10 firearms were confiscated in the raids, according to officials. The sting was a joint operation by the Los Angeles Police Department, the DEA and U.S. Marshals.

The Southern California Drug Task Force stated the gang had operated in the Wilmington area since the 1950s and were affiliated with the Mexican Mafia prison gang.

"This gang has been notorious for major street violence in the area, ranging from murder, attempted murder, assault on police officers, and narcotics trafficking and sales," Lt. Chris Ramirez with the LAPD said.
